The carriage is lockedin its. .lower position by a latch 16' operated by a link -17. connected to the downwardly extendin arm 11 at the left hand side of the machine below the point Y Patented May. 17, 1910. 1907, Serial No. 408,354. Divided and this application filed August Serial No. 511,501. a

at which thelink 10 is connected and there I v is some lost motion between the link 10 and the stud-9.- on the arm 9 en aged. by the linkso that'on rocking 0f sha t 12 the latch 16 is first disengagedfromthe carriage and 'then the carriage 1s shifted. This construction 'is well understood by those familiar 'with the Royal machine.

In order to'shift and lock the carriage in vshifted position, the shift. lock finger piece 18 preferably located at the ri ht hand side of the key board is provided? The lower end of the stem 19 of this latter finger piece is angularly disposed and is pivoted at 20 to a forwardly projectin lever 20 pivoted at 20 adjacent its rear end on'the right hand side plate of the carriage and having applied to its rear .end back of saidpivot a coiled spring 20 the reaction of which normally tends to raise the forward end of the lever .and maintain the shift lock finger piece in normal elevated position against a stop 30. The front end of c'dge of lever 20 is provided with-a recess having a circular or concave wall 21 that coiiperateswith alaterally projecting pin 22 on 'the side of an extension 13 v in rear of the point 13' of that one of the rockshaft arms 13 located at the right hand side of the machine. When in normal position, as

.in Fig. 1, the lower' edge of lever 20 bears on a studbearing upon the pin 22 and consequently when the shift lock finger piece is depressed, the arm 13, and with it the shift finger piece stem 14, is carried downward, rock shaft 12 is rocked and the platen shifted; and, when the stroke. of the stem 19 to effect the shift is completed, 'pin22 passes into the notch in the end of the-lever 20 and engages the concave or circular face thereof as shown in Fig. 2 thereby forming a-toggle lock that holds the platen in elevated or upper position.

Q 4 f ec fillaj case printingposition as long as may. be de'-' sired-. Release of the-platen to permit it'to return to normal position may be'effected by pressure. upon either'efthe shift finger 5 pieces' located respectively .at opposite sides of thekey board, The .eflect of such pressure isto impose upon t-herock shaft a strain tending to move it and to effect sufii -cient movement of arm 13 because of the,

10 elasticity or yielding. bf the parts to disengage pin22 from the notch in the? end of the lever 20, whereupon the lever and stem 19) will be immediately thrown upward to nor mal'position by the action of the spring-20? l5 and on release of'the shiftxfinger piecel5 the platen" will V I claim: I
